Buildings.Electrical.AC.OnePhase.Storage.Battery
Simple model of a battery
Information
Simple model of a battery.
This model takes as an input the power to be stored in the battery (if P > 0) or to be extracted from the battery. This model has a one phase AC connector and takes into account the efficiency of the conversion between DC and AC ηDCAC.
The output connector SOC
is the state of charge of the battery.
This model does not enforce that the state of charge is between zero and one.
However, each time the state of charge crosses zero or one, a warning will
be written to the simulation log file.
The model also does not limit the current through the battery. The user should
provide a control so that only a reasonable amount of power is exchanged,
and that the state of charge remains between zero and one.
Extends from Buildings.Electrical.Interfaces.PartialAcDcParameters (Partial model that contains basic parameters for a DC/AC conversion system).
